The most common criticism of them is that some of them seem to specific. For example, when the Zelda game came out for the wii, a sword and shield set was manufactured for the wii controller that made people feel like it would be cool for the Zelda game, but with a twenty dollar price tag, it suddenly didnt seem so reasonable to own one of these. After all, how many other games could you possibly use this thing for? Why would you pay so much for these all-in-one kits that you might only be using once? It didnt make sense to anyone yet they found enough of a market somehow that they still continue to manufacture special remotes like crazy.
One of the first Nintendo wii kits to come out was for the guitar hero game. This made the most sense because the guitar hero game was one of the first games to ever come out that would actually have the use of their game enhanced exponentially with the use of a special kind of controller. This was made especially for each system because this was meant to make people feel like they were playing a real guitar. Perhaps this idea is what set the bar for the rest of the all-in-one kits that would continue to be manufactured in the future but either way, the first one is the one that made the most sense.
Other all-in-one kits that seemed to be popular at first were the ones that went with wii sports. These were the most sensible purchase at first because it made the most sense. They included the game wii sports with the purchase of every wii, and since there are always new sports games being manufactured all the time, then we can understand how someone would get the most use out of these Nintendo wii kits. Because of their sakes it seemed like a good idea at first, but these Nintendo wii kits and their uses have seemed to spiral out of control recently.
At this point it seems that there are different all-in-one kits available for each wii game out there. At first it was a cool little novelty, having a couple of different Nintendo wii kits available at other times. But now it seems that they are out of control, with a surgical kit for the surgery game and a cooking kit for the cooking game. Though the great thing about them is that there are sites that sell these specialty kits really cheap, like dinodirect.com who sells them for very little? So this way if you ever wanted a kit to make you feel like a chef or a knight you might even be able to find one for fewer than 5 dollars. This would be a bargain, and even if you dont have the games that the kits correspond to, there must be something enticing about using a scalpel to fight an evil wizard or using a spatula to perform heart surgery. Or even using a driving wheel to play guitar. The fun will never end and you will get the most out of your game like this.
